Upgrading rate : Hero Online Submissions

Hi guys, I did my own experiment and found these upgrading rates for hero plus online ( hero online ) and i want to share this for a premium.

When doing this experiment, i had 10002 kc, and i was upgrading with the Dragon Castle Blacksmith. Here are the results:Going from +0 to +1 with 2 gems, the rate is 92%Going from +1 to +2 with 3 gems, the rate is 100%Going from +2 to +3 with 3 gems, the rate is 100%Going from +3 to +4 with 3 gems, the rate is 46%Going from +4 to +5 with 3 gems, the rate is 28%

For each upgrade, I used 50 armors, so going from clean to +1, i used 50 clean armors, from +3 to +4, i used 50 +3 armors
